I have an HP p6130f Pc with an integrated Nvidia 9100 graphics card. It heats up just doing normal things like watching a movie. The picture slows down. What is the best couse of action? I have the case open and have added a cyclone blower fan.

Since you have an integrated card then you can't do anything about that, maybe the chip is "dying" or something... You can buy a cheap dedicated card (HTPC card) for just browsing or watching movies...
